The objective of this study was to evaluate effects of zinc oxide nanoparticles (nano-ZnOs) as a substitute for colistin sulfate (CS) and/or zinc oxide (ZnO) on growth performance, serum enzymes, zinc deposition, intestinal morphology and epithelial barrier in weaned piglets. A total of 216 crossbred Duroc×(Landrace×Yorkshire) piglets weaned at 23 days were randomly assigned into 3 groups, whic...

ZnO-NPs suspended in distilled water were administered to Wistar rats at dose of 10 mg/ kg body weight through oral gavage for 5 consecutive days. The mean body weight gain in rats given ZnO-NPs was similar to this of control group, so no significant differences in the relative organs weight were observed between the ZnO-NPs treated-rats and control. Moreover, ZnO-NPs-exposed rats showed normal...

To provide a front transparent electrode for use in highly efficient hydrogenated amorphous silicon (a-Si:H) thin-film solar cells, porous flat layer and micro-patterns of zinc oxide (ZnO) nanoparticle (NP) layers were prepared through ultraviolet nanoimprint lithography (UV-NIL) and deposited on Al-doped ZnO (AZO) layers. Through this, it was found that a porous micro-pattern of ZnO NPs disper...

The morphology of ultrathin zinc oxide films grown on Pt(111) was studied as a function of preparation and exposure conditions. The results show that submonolayer films exhibit a large variety of structures that may transform into each other depending on ambient conditions. The transformations are accompanied by substantial mass transport across the surface even at room temperature, indicating ...

In this work, we report a direct synthesis of vertically aligned ZnO nanowires on fluorine-doped tin oxide-coated substrates using the chemical vapor deposition (CVD) method. ZnO nanowires with a length of more than 30 μm were synthesized, and dye-sensitized solar cells (DSSCs) based on the as-grown nanowires were fabricated, which showed improvement of the device performance compared to those ...

A zinc oxide (ZnO) nanorod based surface acoustic wave (SAW) sensor has been developed and investigated towards hydrogen (H2) gas. The ZnO nanorods were deposited onto a layered ZnO/64° YX LiNbO3 substrate using a liquid solution method. Micro-characterization results revealed that the diameters of ZnO nanorods are around 100 and 40 nm on LiNbO3 and Au (metallization for electrodes), respective...

In 2008, the modified European Restriction of Hazardous Substances (RoHS) directive prohibited use hazardous substances such as lead, cadmium, and mercury. As such, an urgent need for lead-free components emerged in Europe. this frame, we have decided to study microstructure influence zinc oxide thin films on detection hydrogen sulfide (H2S). Zinc were deposited by PLD silicon substrates under ...

There has been a significant and growing concern over nosocomial medical device infections. Previous studies have demonstrated that embedding nanoparticles alone (specifically, zinc oxide [ZnO]) in conventional polymers (eg, polyvinyl chloride [PVC]) can decrease bacteria growth and may have the potential to prevent or disrupt bacterial processes that lead to infection. However, little to no st...
